So, this piece of string walks into a bar and sits down and says "bartender give me a beer".

The bartender says, "we don't serve pieces of string here, get lost".

So the piece of string goes down the street to another bar and sits down and says "bartender, give me a beer".

The bartender says "we don't serve pieces of string here, get lost".

So now the piece of string is REALLY angry. He thinks to himself, "what I need is a disguise". So he goes back to the first bar, heads straight to the restroom and ties himself in a knot and frizzes the top of his hair out. then he sits down at the bar and says "bartender, give me a beer". the bartender doesn't recognize him and brings him a beer. Just as the bartender set the beer down he said ... "Hey, aren't you that piece of string that was just in here?" and the piece of string said ... " no I'm a frayed knot" ...
